Denton County heads into Monday's start of early voting with 688,032 registered voters, according to figures the Texas Secretary of State posted for the Nov. 3 election. That is 81,757 more than the county had for the last midterm in November 2022, a jump of about 13.5%.
The county's rolls have also grown by 26,467 voters, or about 4%, since the 2024 presidential election, and by 43,691 since the March 2026 primaries, the state's figures show.
Statewide, registration hit a record 19,041,684. The Texas Tribune reported Friday that the total is up 2.2% from November 2024 and 7.7% from the 2022 midterm, with some of the fastest growth in suburban counties such as Kaufman and Ellis.
How the neighbors compare
Denton's growth since 2022 runs close to Collin County's, which climbed to 788,729 registered voters, about 13.7% more than four years ago. Dallas County, the largest in the region at 1,493,955 voters, grew about 5%.
Tarrant County went the other way: it has 32,503 fewer registered voters than in 2022, a 2.6% drop, which the Tribune noted makes it the largest county in the state to lose voters over that span.
About 1 in 10 are on the suspense list
Of Denton County's registered voters, 73,785, or about 10.7%, are listed as suspense voters, compared with 9.3% statewide. Suspense means the registrar is not certain of a voter's home address, often because a registration certificate, jury summons or other mail came back undeliverable, according to the state's VoteTexas site.
Being on suspense does not keep someone from voting. A voter on suspense who still lives in the same county can cast a ballot after filling out a statement of residence at the polls, the site says. Voters who have moved to a new county may be able to cast a limited ballot at the main early voting location during early voting.
